Coincidence? Perhaps. But coincidence has a relatively minor place in the
Wold Newton Universe. Far more of what takes place seems to be guided by
what narrativium. From the soul of a dying man manifesting as a bat and inspiring
Bruce Wayne to freak visits to the distant past, much of what takes place
in the WNU is not coincidence, but rather deliberate manipulation of events.
(By who is another question, and one beyond the scope of this note to explain).
So consider this: which "unhallowed damps of the grave" (his own words)
did Victor Frankenstein visit? Whose bodies did Victor use to make his Creature?
Is not merely possible but likely that a part of Florian Geier--perhaps
only a femur, perhaps as much as a skull--was incorporated into the Creature's
body?

#2. History records that Jonathan Wild was executed at Tyburn in
1725. But history also records that Claude Duval died in 1670, and we know
that to be false. The sad truth is that record-keeping was intermittent in
earlier centuries, and much of what has previously been confidently stated
as true--for example, that the first trip to the Moon took place in 1969--is
quite false. So, too, with the deaths of Wild and Duval.

Unfortunately, it is also true that researchers looking at the Wold Newton
Universe are occasionally faced with two or more contradictory biographies
and are forced to choose between them and to decide which is the true one
and which is not. In this case, Edward Viles' Blueskin is the correct
one, and William Harrison Ainsworth's Jack Sheppard (1839) must reluctantly
be dismissed as pure fiction.

#3. As with the two contradictory histories of Jack Sheppard (see
note #2 above), there are two contradictory biographies of the so-called "Blue
Dwarf:" The Blue Dwarf. A Novel (1860-1861), by "Lady Esther Hope,"
and The Blue Dwarf: A Tale of Love, Mystery and Crime (1874-1875) by
Percy B. St. John. The contradictory elements come not from the same figure
appearing in both accounts, but rather two different people suffering from
almost the exact same life story and given the same nickname. Clearly, one
of these is an erroneous version of the true figure's story, and the erring
account is the first one.

#4. Clearly Blueskin returned from France some time after the end
of Blueskin.
